according to the illumination intensity information processing method, through filtering, noise elimination or correction on illumination intensity information acquired by the sensor, accurate perception of the illumination level of the surrounding environment by the system is improved, and the generated uniformity regulating signal (BCS, CMCS, UTV) allows fine regulation of the brightness, the light distribution and the illumination uniformity of the LEDs, so that the display effect is optimized.
Through preliminary processing of color value information and normalization processing of color temperature information, the system generates color regulation signals, including light distribution regulation signals, color regulation signals based on the color value information and color regulation signals containing basic colors, chroma and whiteness, so that the LEDs can adjust colors more accurately and dynamically to adapt to different environments and user requirements.
The reference positioning method can realize intelligent adjustment of the terminal display module, and by judging translational acceleration information and displacement change in a sampling interval, the system can generate an adjusting signal and inform the terminal display module to adjust corresponding display content, so that the user's experience is improved, and the display content can be kept relatively stable in the moving process of the terminal.
